使用Alamofire 4在正文中包含数据的POST请求

import Alamofire

let parameters: Parameters = [
    "username": "exampleUser",
    "password": "examplePassword"
]

Alamofire.request("https://api.example.com/login", method: .post, parameters: parameters, encoding: JSONEncoding.default)
    .responseJSON { response in
        switch response.result {
        case .success(let value):
            print("Response JSON: \(value)")
        case .failure(let error):
            print("Error: \(error)")
        }
    }

Alamofire.request("https://api.example.com/login", method: .post, parameters: parameters, encoding: JSONEncoding.default)
    .responseJSON { response in
        switch response.result {
        case .success(let value):
            print("Response JSON: \(value)")
        case .failure(let error):
            if let error = error as? AFError {
                switch error {
                case .networkFailure(let error):
                    print("Network Failure: \(error)")
                case .serverTrustFailure(let error):
                    print("Server Trust Failure: \(error)")
                case .requestSerializationFailed(let error):
                    print("Request Serialization Failed: \(error)")
                case .responseValidationFailed(let error):
                    print("Response Validation Failed: \(error)")
                case .responseSerializationFailed(let error):
                    print("Response Serialization Failed: \(error)")
                default:
                    print("Unknown Error: \(error)")
                }
            } else {
                print("Unknown Error: \(error)")
            }
        }
    }
